Parachute for classic gamebuino

Hi all, i have made a game somes week ago after completing to mount my Makerbuino.

The game is functionnal but can be better with your help. I need to improve the gameplay. I would be more near than the original parachute game for the moves of the boat and the timing of the fall of the parachutes. All your remarks and propositions to perfect it are welcome.

I would complete it to try later to make it better with a port for my META when i'll receive it.
